Whats your game of the year?

Every one knows Bioshock by 2k for the 360 won game of the year by far and also alot of other awards. But what was your favorite game of the year

BioshockThe winner for me was Bioshock.It was a fight between COD4 and Bioshock but if you really think about it Bioshock had it all. Great story line, perfect game play, all the way down to the sound.
